Transcranial Alternating Current Stimulation for Modulation of Sleep and Cognitive Performance
This study will investigate the effect of transcranial alternating current stimulation on sleep and cognitive performance in cognitively normal older adults and in individuals with mild cognitive impairment (MCI).

Transcranial alternating current stimulation uses electrodes to deliver small amounts of electricity through the brain. In this study, researchers will investigate the effect of stimulation on sleep, thinking and memory, mood, and quality of life. Participants will undergo either transcranial alternating current stimulation or sham stimulation during slow-wave sleep.
Loss of slow-wave sleep is common in people with MCI and Alzheimers disease and is thought to worsen thinking, memory, and brain degeneration. Transcranial alternating current stimulation has been demonstrated to enhance slow-wave sleep and improve memory in healthy adults. This research will investigate the effect of the stimulation on both cognitively normal older adults and those with MCI.
